Some researchers claim there is an association between taking vitamins and gaining weight. They took a random sample of people living in Boston, Massachusetts, and recorded whether they took vitamins and whether they gained weight. The results are shown in the following two-way table:


Has Gained Weight Has Not Gained Weight
Does not take vitamins 52 19
Takes one vitamin per day 35 49
Takes more than one vitamin per day 72 80


If a person is chosen at random, what is the probability that he or she has gained weight, given that he or she takes more than one vitamin per day?
0.42
0.45
0.47
0.50

Answer:

77 units^2

Step-by-step explanation:

I'm going to call the red square A, green square B, blue square C.

A side of a square is the square root of the area.

The Pythagorean Theorem is A^2 + B^2 =C^2.

So in other words,  

33 + 44 = the side of square C^2.

33+44=77

One side of square C is √77.

Square this to get the area.

Square C's area is 77 units^2.

Answer: year 1948

Step-by-step explanation:

1900 is our t = 0

The population of Greenville can be written as:

G = 4000 + 100*t

the equation for Springfield can be written as:

S = 1000*(1.04)^t

we want to find the value of t that makes S(t) = G(t)

4000 + 100*t = 1000*(1.04)^t

(4000 + 100*t) = 1.04^t

4 + 0.1*t = 1.04^t

now, you can graph both of this equations (left side and right side) and see in wich value of t the graphs intersect eachother, or you also may use different values of t until the values are about the same for both sides, which is the thing i did with the equation:

4 = 1.04^t - 0.1*t

You will find that the correct value is t = 48

So we can assume that in year 1948 the populations will be about the same.

Answer:

The speed at which the buss made the trip was 45 mph and the train was 57 mph.

Step-by-step explanation:

The average speed is given by:

speed = distance / time

Therefore we can manipulate it to give us the distance:

distance = speed*time

The time distance of each stage of his trip summed must be equal to the total distance of the trip. Since he made a trip in two legs, one by bus that lasted 3 h at a speed of "x" and one that lasted 5 hours at a speed of "x + 12". We have:

420 = 3*x + 5*(x + 12)

3*x + 5*(x + 12) = 420

3*x + 5*x + 60 = 420

8*x = 420 - 60

8*x = 360

x = 45 mph

The speed at which the buss made the trip was 45 mph and the train was 57 mph.

Answer:

45 mph

Answer:

Dilation factor is 2/3

Step-by-step explanation:

Look at both flat lines (M to S and M' to S') and find their lengths.

M to S = 9 units

M' to S' = 6 units

The triangle has gotten smaller so the dilation factor is a fraction

new/original = 6/9 = .66666666 or 2/3

Dilation factor is 2/3

The size in the x direction did not change but the y direction did change so

Answer:

-23

Step-by-step explanation:

x = -5 lies in the last piece

h(-5) = 4(-5) - 3

= -20 - 3

= -23

Step-by-step explanation:

Step 1:  Find which piece-wise function it is in

Equation 1 → x < -7

Let x = -5 → (-5) < -7 ← False

Equation 2 → -7 ≤ x < -5

Let x = -5 → -7 ≤ (-5) < -5 ← False

Equation 3 → x ≥ -5

Let x = -5 → (-5) ≥ -5 ← True

Step 2:  Find the value of h(-5)

[tex]h(-5) = 4x - 3[/tex]

[tex]h(-5) = 4(-5) - 3[/tex]

[tex]h(-5) = -20 - 3[/tex]

[tex]h(-5) = -23[/tex]

Answer:  [tex]h(-5) = -23[/tex]

Answer:

It is not a linear function

Step-by-step explanation:

There is a one to one correspondence and this would pass the vertical line test

This is a function

However, the questions asks if it is a linear function, which would mean is it a straight line.

This curves, so it is not a linear function

Answer:

91.2

Step-by-step explanation:

If there is 57 ounces in 5 boxes and you divide 57 by 5 you'll get 11.4. After that you should times 11.4 by 8 to get 91.2 ounces

Answer:

91.2 ounces

Step-by-step explanation:

Let's make a proportion using this setup:

ounces/boxes=ounces/boxes

There are 57 ounces in 5 boxes, and x ounces in 8 boxes.

57 ounces/5 boxes= x ounces/8 boxes

57/5=x/8

Now we have to solve for x. x and 8 are being divided. To undo this, multiply both sides by 8, because multiplication is the opposite of division.

8*57/5=x/8*8

The 8s on the right will cancel, so we are left with:

8*57/5=x

8*11.4=x

91.2=x

There are 91.2 ounces in 8 boxes

Answer:

(4, -3)

Step-by-step explanation:

The origin is at (0,0). When you move right or left, you change the x-coordinate, or the first coordinate. You moved right which is in the positive direction so now your coordinate is (4,0).

When you move up or down, you change the y-coordinate, or the second coordinate. You moved down which is in the negative direction so your final coordinate is (4, -3).

Answer:

  6.75

Step-by-step explanation:

The shaded area amounts to two congruent equilateral triangles. Each has a side length of 2(1 in)cos(30°) = √3 in.

The height of an equilateral triangle with side length √3 is ...

  height = (√3 in)sin(60°) = 3/2 in

Then the area of the two equilateral triangles is ...

  A = bh = (√3 in)(3/2 in) = 3√3/2 in^2

The square of the numerical value of the area is ...

  A^2 = ((3/2)(√3))^2 = 27/4 = 6.75

The square of the shaded area is 6.75.

[tex]\frac{1}{125}[/tex]

Step-by-step explanation:

The given expression is

[tex](5^{-2}) (5^{-1})[/tex]

The expression is about two powers with the same base, so we can use the power property of multiplication, which states that we must proceed we writing only one base and sum exponents

[tex](5^{-2}) (5^{-1})=5^{-2-1}=5^{-3}[/tex]

Then, we use the negative exponent property

[tex]5^{-3}=\frac{1}{5^{3} }[/tex]

Finally, we solve the power

[tex]\frac{1}{5^{3} }=\frac{1}{125}[/tex]

Therefore, the given expression is equivalen to [tex]\frac{1}{125}[/tex].

81x4^ + 108x^3y^2 + 54x^2y^4 +12xy^6 +y^8

Step-by-step explanation:

Step-by-step explanation:

m∠1 = 180-100 = 80

m∠2 = 180-150 = 30

m∠3 = 180-(80+30) = 180 - 110 = 70

using the law of sine :

AC/sin(m∠2) = 5/sin(m∠3) ⇒ AC = sin(m∠2)*(5/sin(m∠3)) = sin(30)×(5÷sin(70))

=2.66044443119

CB/sin(m∠1) = 5/sin(m∠3) ⇒ CB = sin(m∠1)*(5/sin(m∠3)) ⇒ CB = sin(80)×(5÷sin(70)) = 5.240052604588
